Ok everyone I need some help. I put the carbs back on and added some gas. I got it started but it keeps bogging out on me. When I give it gas it wants to die and sometimes it idles good and sometimes it doesn't. I'm getting back firing too when I give it gas. Also, when i give it gas it sounds like it's sucking a lot of air but I do not know much about carbs and all. I rebuilt the carb according to instructions and made proper adjustments with float and all. I backed out the air mixture screws 2 turns and then tried them at 1 and a half turn but nothing really changed. I am noticing some air leaking out of the front right bolt area where the carb bolts to the engine on the throttle side. I do not understand how air is leaking from there. Does anyone have any ideas? I also cleaned out all plugs. They were black. Any help is very appreciated. Here are some crappy pics. I had a little mishap with my cell phone and now the pictures look weird.
This is the where the air is leaking from the bolt.
